概括
计算机断层扫描 (CT) 与计算机断层扫描血管造影 (CTA) 一样有效,用于深下腹膜动脉穿孔器 (DIEP) 板的手术前规划. 这一发现可以减少患者的辐射和对比暴露,提高资源利用率.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 对于深部下腹动脉穿孔器 (DIEP) 片的术前成像对于通过识别合适的穿孔器来优化手术时间至关重要.
- 专用计算机断层扫描血管造影 (CTA) 是当前的黄金标准,但许多患者已经接受了用于瘤目的的分期计算机断层扫描 (CT).
- 使用分期CT或CT与静脉注射对比剂可以提供与专用CTA相似的好处.
研究的目的:
- 为了比较分阶段计算机断层扫描 (CT) 与计算机断层扫描血管造影 (CTA) 的疗效,用于识别深下腹上动脉穿孔器 (DIEP) 片的穿孔器,进行手术前规划.
- 评估CT和CTA之间的穿孔器位置的相关性.
- 为了评估每个成像模式所识别的穿孔器的数量.
主要方法:
- 一项回顾性研究包括十名患者,他们在三年内接受了DIEP片重建,并分阶段CT和CTA.
- 审稿人独立评估了两种成像方式的轴视图,以识别和定位相对于交错的可见穿孔器.
- 类内相关系数 (ICC) 用于确定穿孔器位置的一致性,统计分析包括Wilcoxon签署的等级测试.
主要成果:
- 根据ICC的说法,在CT和CTA上发现的穿孔器位置之间发现了很好的相关性.
- 发现的穿孔器的平均数量在两组之间是可比的:CT的15.3 (SD 4.9) 和CTA的18.8 (SD 6.4).
- 在CT和CTA之间确定的穿孔器数量的差异在统计学上并不显著 (P = 0.247).
结论:
- 计算机断层扫描 (CT) 显示出与专用计算机断层扫描血管造影 (CTA) 相似的有效性,用于识别DIEP片的手术前规划中的穿孔器的数量和位置.
- 这一发现表明,分期CT可以成为专用CTA的可行替代方案,可能减少患者暴露于对比剂和电离辐射.
- 采用分期CT可能会改善患者的治疗结果,并更有效地利用医疗保健资源.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
91
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
